An external armature current actual value can also be connected to this input (see FP6902).
The 3 inputs AI 0, AI 1 and AI 2 of a CUD on the left and the 3 inputs AI 0, AI 1 and AI 2 of a CUD on the right can be
operated so that they are averaged during the same measuring interval. The 6 mean values are provided on 6 BICOs
(see FP2083).
